Note 10) The PD output is placed in the "Source" status when the phase of local oscillator div ision output is behind the phase comparison f requency. It is placed in the "Sink" status when the phase of local oscillator div ision output adv ances. 11) " " means high impedance status.
12) When the phase dif f erence that is 8 times or less* of the OSC f requency c ontinues 15 or more cy c les of comparison f requency (Fref ), LOCK output is placed in the "L" status. (*625ns when a 12.8MHz oscillator is used) 13) When the power supply of each sy stem is turned of f , the LOCK output status goes to "H". 14) The LOCK output circuit is an open drain output of t he N channel MOS transistor.

Cautions for Handling Application Board
* For the achiev ement of high perf ormances in the MIX system, the 50ohm-matching is necessary in the MIXIN port. * Please place external elements connected to the RF line, near the pins. (Especially , resisters of TXOUT, TXE, and RXE) * The VCC/TXVCC/RXVCC decoupling capacitances are important f or the achiev ement of high perf ormances. Please place these elements near the pins. * In this diagram, coef f icients of the X'tal oscillation circuit are merely examples. Please ask X'tal unit v endor about the best v alues of customer's specif ication.
